File Explorer - hakakou/optiperl GitHub Wiki
The file explorer can be used to browse a folder and open files. Right clicking on a folder or file will open a standard explorer menu.
Double-clicking a file associated with OptiPerl will open it.
You can also select a set of folder and files and do a pattern search / replace on them. The results of the search or logging of the replacements will show in the code explorer window. To open the dialog, press the find button (rightmost button).
